To all whom it may concern:

Be it known that 1, JOHN F. OCoNNoR, a citizen of the United States,residing at 0hr cago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Railway-Car Draft-Riggings, of which the following is a full, clear, concise, and exactdescription, reference being had. to the accompanying drawings, forminga part of this specification.

This invention relates to improvements in railway car draft riggings.

Objects of the invention are to provide a draft'rigging for railway,cars which comprises few parts, compactly arranged and readily assembledand disassembled.

Other objects of the invention are the provision of: A rigging forrailway cars wherein a oke is detachably connected to the draw-bar; ayoke comprising two members and together having a' friction shellformedintegrally therewith; integral means on the two pieces of the yoke andelements of the friction mechanism which cooperate to prevent lateralseparation of the yoke members;

- and a single fixed key by which all the bud and draft shocks aretransmitted to the sills, said key preventin rearward movement of theyoke under bu and preventing forward movement of certain elements of thefriction mechanism under draft.

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices, asherein shown, described and claimed. i

In the drawing forming a part of 12,213 specifica ion, Figure 1 is acentral, longit inal vert cal section view of a draft rigging embodyingmy improvements, the coupler being shown in side elevation. Fig. 'is ahorizontal combined sectional and plan view, the r on t e line 22 ofFig. 1. Fig. 3 is a transverse vertical sectional viewi taken on theline 3-3 of Fig. 1.1 Fig. 4 is a view similar to Fig. 3 illustratinganother embodiment Speoiflcation of Letters Patent.

inforcing plates 1111, said plates and sills being slotted to 'removablyreceive therethrough a relatively fixed transverse key 12', the keybeing held in place by any suitable means such as cotters 13. Thedraw-bar 14: is shown as of the M. C. B. type and provided with upperand lower shoulders 15 with which cooperate under draft, inturnedshoulders 16 formed at the front ends of two loop-like members 1717which together form a'yoke designated generally by the ref- 'erence A.Each of said yoke members 17-17 is preferably of like construction andcomprises an upper arm 18, lower arm 19 and side wall 20 which extendsfrom the front to a point somewhat to the rear of the longitudinalcenter thereof. The upper and lower arms 1819 of each yoke member areprovided on their inner faces, as clearly indicated in Figs. 1 and 3,with friction suffaces 21-21, each of said surfaces as shown in thestructure illustrated in. Fi s. 1 to 3, being longitudinally grooved asi dicated at- 22. Reinforcing ribs 23 are provided on the outer surfacesof the yoke members surrounding the friction shell formed integ-' 27.The sides 20 of th'e'yoke members are also provided with elongated slots28 through which the key 12 extends, said slots being so arranged thatthe yoke is permitted'forward movement relatively to. the key but isprevented from rearward movement. Said slots 28 are surrounded bylaterally extendin'g flanges 29 arranged to strengthen the 1yoke andalso to assist in centering the yoke etween the center sills.

As clearly shown. in Fig. 1, the follower wedge block 27 has anelongated centrally located slot 30 through which the key 12 extends,said slot 30 being open at its front end and s0 arranged, as to permitthe in ward. movement of the wedge but preventing its outward movement.The friction shoe-26 and wedge'block 27 areprovided with inclined facesinthe usual manner and having anti-friction rollers 31 therebetween.

,As most clearly shown in ,Fig. 3, each of the friction shoes26 isprovided with a pair of integral longitudinally extending ribs 32arranged to'slide and engage in the longie Milo ,lly eiitehding grooves22 fort-iced on llllkfilf' feces of the friction shell portions interi Ieduelly compres ed U11- is prevented from thus causing the $38.1 conportion oi the yoke to serve: as e v p for the spring 24:.
